Aluminum pipe wall thickness. fitting vs welded
I have been using an NRS frame for my WW boat. I love it, but I've been thinking of welding one together over the winter. It looks like most frames that utilize fittings (lopros, speed rail or similar) are schedule 40. I'm guessing the are thicker and heavier because they are compressed by the fitting. Can I go to a smaller wall thickness that will keep the strength since it will be welded together?
